Adjustment Procedures Results of Improper Adjustment

A. Procedure by removing the gear box large lid (Standardadjustment) (A-SR)

1) Remove the gear box large lid. (Refer to 4-(1).)2) Adjust the engraved marker line on the thread take-up to timing

mark G on the face plate.3) Align the timing mark on the feed adjustor with the engraved

marker dot on the machine bed. <<Confirmation of the standard timing>>

4) Timing mark of the feed rocker cam aligns with that of the feedrocker rod. ... Standard state

Standard assembling adjustment is described below.5) When they do not align with each other, loosen two setscrews

8 in the hook driving shaft sprocket, and it is necessary toalign the timing mark of the feed rocker cam with that of thefeed rocker rod.

6) Tilt the machine head, remove feed stepping motor connector1, and remove feed lever spring 2 from the spring bracket.

* When removing feed lever spring 2, perform the work using theradio pincers or the like.

7) Loosen two setscrews 3 in the feed stepping motor link C anddraw out feed link shaft 4 to the right-hand side.

8) Remove three setscrews 5 in the feed stepping motor unit.9) When removing the feed stepping motor unit, remove oil pipe

7 from oil pipe guide 6.10) In the state of 3), loosen two setscrews 8 in the hook driving

shaft sprocket, and adjust the timing mark on the feed rockercam to that on the feed rocker rod.

11) When re-assembling the feed stepping motor unit, refer to 3-(3)-2) Adjusting the feed amount.

B. Procedure with the gear box large lid installed (For fineadjustment) (A-SR)

It is possible to check standard timing without opening the gearbox large lid.

1) Adjust the engraved marker line on the thread take-up to timingmark F on the face plate.

2) It is the standard timing that the top surface of feed dog almostaligns with the top surface of throat plate when the feed dogsinks. However, the height of feed dog is 1.2 mm at the time ofstandard delivery.

3) Align the timing mark on the feed adjustor with the engravedmarker dot on the machine bed. (When feed amount is “0”)

4) When they do not align with each other, loosen two setscrews8 in the hook driving shaft sprocket and adjust the timing.(For the adjustment procedure, refer to the aforementioneditems 1) through 6).

* Adjusting the feed timing (Common to A. and B.) By performing the feed timing adjustment, stitch tightness

changes and sewing quality is improved according to theprocess.

™ When oil pipe guide 6 is forciblydrawn, the oil pipe comes off ordamaged. As a result , oi lleakage will be caused.

™ When changing the feed timingother than the standard one, itis easy to adjust when thestandard state is made a basis.

* When changing the feed timingother than the standard one, andsewing patterns that performnormal/reverse feed motion (Tstitch, custom pattern, etc.),needle may bend according tothe feed amount (needle snaps).In this case, change the feedtiming from the panel andcompensate.

™ Timing mark on the feed adjustoris the inside mark. (Common toA. and B.)

[Feed 0 adjustment]For the adjustment of feed 0 position, perform fine adjustment of the

direction of rotation of feed adjustor 1.1) Tilt the machine head and loosen two setscrews 2 in the stepping

motor link C.2) Adjust feed link shaft 3 to the slippage amount of feed using a slotted

screwdriver and temporarily tighten two setscrews 2 in the steppingmotor link C.

* Feed link shaft 3 consists of eccenric pin.

3) Return the machine head to the home position, turn ON the power, setthe operation panel to straight stitching, and set normal feed amountto “0”.

* Set the speed variable resistor of operation panel to the extreme leftend and set the sewing speed to 200 rpm.

4) Insert a sheet of paper under the presser foot and depress the pedalto operate the sewing machine.

At this time, check the needle entry on the paper to check that feedamount becomes “0”.

5) When feed amount is “0”, tilt the sewing machine head after turningOFF the power and securely tighten two setscrews 2 in the steppingmotor link C.

After securely tightening the setscrews, check that feed adjustor 1smoothly moves with the presser foot lifted.

When the feed amount does not become “0”, turn OFF the poweragain and repeat the work of steps 1) and 2).

[Feed 0 adjustment] : When feed amount does not become “0” byadjusting feed link shaft 3 only.

1) Loosen three fixing screws 4 in the feed stepping motor unit andperform the vertical adjustment of feed stepping motor unit 5.

2) After the adjustment, check that feed adjustor link 6 smoothly moveswith the presser foot lifted.

3) The standard that feed adjustor link 6 smoothly moves is the feedmechanism torque (less than 700g by the spring balancer) beforesetting the feed stepping motor unit. (Be sure to perform the centeringwork so that the torque is less than 1,000g.)

[Normal/reverse feed amount control]1) Input max. feed amount limitation value of normal/reverse feed with

the information of operation panel* For the information operation, refer to Instruction Manual.* Normal/reverse feed amount has been factory-set to the standard

adjustment value of JUKI standard delivery gauge (Part No. 40018430... max. feed amount of normal/reverse stitching is 5 mm).

There are cases where the feed amount varies from the actual inputvalue in accordance with the material used or kind of gauge. Thenperform the input compensation.

Adjustment Procedures Results of Improper Adjustment

™ Start the work of the feed amount“0” adjustment after performing 3-(2)-2) Adjusting the feed timing (A-SR only).

™ When there is a torque, one-sidedworn-out of feed link or step-out offeed stepping motor 5 will becaused.

2. There are grease grooves in the both ends of bushing of feed stepping motor link A asm 2. and a grease filling hole inside feed stepping motor connecting shaft 1. Fill those parts with exclusive grease (can type part No. 23640204 or tube type part No. 40006323).3. Connect feed stepping motor link B 3 and feed stepping motor link A asm. 2 after making the looseness in the shaft direction as small as possible.

Zigzag timing can be changed.

Needle sway can be prevented by delaying timing when sewing heavy-weight materials or the like.

1. Fast : Standard setting

2. Slow : Timing is delayed by approximately 30fl in terms of the standard.

However, to delay timing, conditions below are necessary.1. When the number of rotation is set to less than 4,000 rpm with the function setting No. 96, Max.

number of rotation setting.2. When the travelling distance of 1 stitch is less than 4 mm.

In case of more than 4 mm, needle may travel while it is stuck on the cloth.In case the distance is more than 4 mm and zigzag motion is performed, do not set this function.

3 : Change of feed timing (LZ-2290A-SR only) When adjusting the heigt of feed dog or hook driving shaft sprocket timing, feed dog is fed while needle

is stuck on the cloth according to the feed pitch amount. As a result, needle bend will be caused. In this case, perform the adjustment of the phase of feed timing. Setting range : -50 º to + 50 º in terms of the standard timing

7 : Alternate changeover of stitch base line unit between 0.1 mm and 0.2 mm

The unit of change of stitch base line position can be changed over to 0.1 mm unit or 0.2 mm unit.

1. 0.1 mm unit : Standard setting

2. 0.2 mm unit : Panel setting is 0.1 mm unit, but actually the position travels every 0.2 mm.
